Abstract: A multi-dimensional assembly of time/velocity functions are sampled for velocity as a function of incremental time. The samples are stored in a matrix arranged in columns along the time axis and rows across the velocity axis. The count of the number of samples resident in the respective cells of each row is indexed. A desired statistical operator is applied to the count indices in the rows to provide a family of filtered histograms in time-sequential order. The filtered histograms may be edited by delimiting acceptable velocities to lie between preselected percentiles.

Abstract: Etoposide phosphate is prepared by coupling dibenzyl 4'-demethyl-4-epipodophyllotoxin-4'-phosphate with 2,3-di-O-benzyl-4,6-0-ethylidene-a,.beta.-D-glucopyranose in a solvent and subsequently removing the protecting groups.  The tetra-benzyl protected etoposide phosphate is recrystallized from methanol or directly crystallized from acetonitrile by adding methanol to yield substantially the pure C-1"-.beta. form.  The benzyl protecting groups are simultaneously removed by hydrogenation to produce etoposide phosphate in high yields.  In a further embodiment, etoposide phosphate is treated with a phosphatase enzyme to yield etoposide.

Abstract: Two dichroic mirrors (26,30) and a dichroic beamsplitter (36) are introduced into the conventional Michelson Fourier transform spectrometer to accommodate two spectral bands. A conventional Michelson Fourier transform spectrometer (FTS) uses two mirrors (20,22), one fixed (20) and the other moving (22). The present invention replaces each of the two mirrors (20,22) with a pair of mirrors, one of which is a di-chroic mirror (26,30). The present invention involves inserting the first dichroic mirror (26) fixed in position between the beamsplitter (12) and the first plane mirror (20) and inserting a second dichroic mirror (30), which can be moved in a direction normal to the plane surface, between the beamsplitter (12) and the second plane mirror (22). The first dichroic mirror (26) and second dichroic mirror (30) transmit long wavelength radiation and reflect short wavelength radiation. A dichroic beamsplitter (36) is also inserted in the interferometer assembly (10) to separate the two spectral bands in the third beam (24). By moving the second plane mirror (22) and the second dichroic mir-ror (30) a different amount to change the optical path difference between the second plane mirror (22) and the beamsplitter (12), and the optical path difference between the second dichroic mirror (30) and the beamsplitter (12), two spectral bands can be proc-essed with different spectral resolutions.

Granted: 2002-07-30
Abstract: A five-piece container for items, such as bottles, comprises a bottom piece, a pair of side pieces of identical height and a pair of end pieces also of identical height; each side edge and each end edge of the bottom piece display a series of planar surfaces interspaced with a series of recessed areas in which is defined a hinge that engagedly receives a C-shaped extension formed at the lower edge of each side piece and of each end piece so that the side and end pieces may be mounted to the bottom piece through a snap . The end pieces and the side pieces can be moved between an outward foldback position and an erected position; however, an inward folded position cannot be effected due to the configuration of the lower edge of the side pieces and of the end pieces and that of the edges of the bottom piece. The folding configuration is useful for containers that have walls higher than the width of the bottom thus preventing the walls from being folded inside.

Granted: 1999-10-05
Abstract: A crusher capable of effectively crushing a building structure, shearing iron reinforcing rods, etc., smashing the crushed scraps into pieces, and collecting and carrying an elongated object. A pair of arms (2a, 2b) are driven to open and close for crushing and shearing the object. A front end of each of the pair of arms is divided into a plurality of fingers to which claws (7a, 7a', 7b) are respectively attached. Only the central claw (7a') is inwardly directed by a greater angle as compared with the other claws (7a, 7b). Each arms has a shearing blade (10a, 10b) for shearing an iron reinforcing rod, an iron frame, etc. in the vicinity of the pivoted portion, and also through holes (11) in the central portion. Weight of the arms (2a, 2b) and an arm support (3) are balanced with respect to the central axis of rotation of the arm support (3). The central claw (7a') gives a concentrated stress to the building structure to cause cracks when the arms (2a, 2b) are closed, thereafter the object is squashed out by all of the claws (7a, 7a', 7b). Concrete scraps are smashed by the central portions of the arms and flow out from the through holes.

Abstract: A control circuit and method are provided for a circuit interrupter that predicts the occurrence of fault-current zero crossings. This prediction is utilized to control the operation of a circuit interrupter at a desirable point in the periodic wave form of the fault current. For example, the control circuit is useful to control a synchronous interrupter by accurately generating a trip signal to the synchronous interrupter for operation in the vicinity of the zero crossing of the current wave form. In a preferred arrangement, the control circuit utilizes the quotient of a sensed current signal and the time rate of change of the sensed current signal. In one specific arrangement for circuit environments that might include conditions that could lead to false results, the time rate of change of the quotient is utilized to provide a control signal.

Abstract: A cord comprising at least a first pair and a second pair of wires (2a, 2b) of different diameter randomly disposed in transverse cross section thereof, is obtained by arranging in a nacelle (7) of a double-twisting laying machine, a twister (16) operating upstream of a preformer (15). The twister (16), rotating in a direction opposite to that of the impeller (5) and at a speed which is twice that of the impeller, neutralizes the internal torsional stresses induced in the wires (2a, 2b) by effect of the double twisting carried out upon the action of the impeller itself. Thus, a better control of the preforming operation executed on the wires (2a, 2b) disposed parallel in respectively coplanar axes is enabled. The obtained cord (1), within each laying pitch and only under a traction condition involving a load not exceeding 5 kg, has at least one right cross section in which at least one wire (2a, 2b) is spaced apart from at least one of the adjacent wires so as to facilitate the rubberizing step, by enabling access of the blend to the cross section and penetration thereof along the cord axis. The cord is preferably used as a reinforcing element for the belt structure.

Abstract: Shaving compositions for use in the personal shaving process with a razor blade assembly include insoluble solid particulate additives. The shaving compositions may include one or more of the following: wetting agents, cleansing agents, lather producing compositions, emollients and mixtures thereof; and further includes at least one solid, insoluble particulate additive in a well dispersed suspension throughout said shaving composition. The solid additives are present in an effective amount to produce physical microscopic support for the blade of a razor blade assembly during the personal shaving process. By providing micro-support of the razor blade parallel to skin surface and above surface irregularities, the solid particulate additives provide improved razor blade glide, thereby preventing nicks and cuts, and also enhancing exfoliation of dead skin and removal of grease and oils, as well as improving hair extraction prior to cutting, thereby improving overall smoothness of the post-shaven skin. The shaving compositions may be in the form of a gel, cream, solid, liquid or aerosol before and/or after application to the skin.
